Description

TECHNICAL FIELD

[0001] The present utility model relates to the field of heat treatment of metallic materials, in particular to an electromagnetic induction normalization device for rail seam welds. STATE OF THE ART

[0002] Nowadays, more and more seamless rails are being laid, and in most cases, short pieces of rail are used, which are welded and heat-treated into seamless rails. Post-welding normalizing is an essential step. However, because seamless rails require on-site normalizing, current equipment is unsuitable for some special working environments such as tunnels, railway platforms, etc.

[0003] The specification of the Chinese Utility Model Patent Application Laid-Open CN111331041A discloses a separable and combinable electromagnetic post-forming induction heating device. This induction heating device includes a movable carriage, a left box unit, a right box unit, a cooling water tank, and an induction power supply. The separable and combinable toothed electromagnetic post-forming induction heating device crosses over each other to facilitate complete heating and make the surface temperature more uniform. Furthermore, the provision of two boxes, namely the left box and the right box, results in no restriction on the heating position. Furthermore, the provision of a ball screw allows for height adjustment in the direction perpendicular to the floor, so this induction heating device can be used on rails of different heights in different factories.

[0004] However, this device is not suitable for on-site heating of underground tunnels or long ground tracks. It requires not only constant switching between the two tracks during on-site operation, but also a rapidly movable and stable support structure. This device is therefore very impractical to use.
